isVisible

Determine visibility of scope

Syntax

visibility = isVisible(scope)

Description

visibility = isVisible(scope) returns the visibility of the scope as logical, with 1 (true) for visible.

Examples

View Sine Wave on Time Scope

Create a time-domain sinusoidal signal. Display the signal by calling the time scope object.

Create a sinusoidal signal with two tones, one at 0.3 kHz and the other at 3 kHz.

t = (0:1000)'/8e3;
xin = sin(2*pi*0.3e3*t)+sin(2*pi*3e3*t);

Create a timescope object and view the sinusoidal signal by calling the time scope object scope.

scope = timescope(SampleRate=8e3,...
    TimeSpanSource="property",...
    TimeSpan=0.1);
scope(xin)

Run release to allow changes to property values and input characteristics. The scope automatically scales the axes.

release(scope);

Hide the scope window.

if(isVisible(scope))
    hide(scope)
end

Show the scope window.

if(~isVisible(scope))
    show(scope)
end

Input Arguments

scope — Scope object

timescope object

Scope object whose visibility you want to query.

Example: myScope = timescope; visibility = isVisible(myScope)

Output Arguments

visibility — Scope visibility

1 | 0

If the scope window is open, the isVisible function returns 1 (true). Otherwise, the function returns 0 (false).
